Stumping for Democratic presidential candidate Bernie Sanders on Tinder is getting some women banned from the online dating app after sending campaign messages to prospective matches.Two women - one from Iowa and the other from New Jersey - confirmed to Reuters on Friday that they received notices from Tinder in the previous 24 hours that their accounts were locked because they had been reported too many times for peppering men on the site with messages promoting Sanders' candidacy.Robyn Gedrich, 23, said she sent messages to 60 people a day for the past two weeks trying to convince them to support the U.S. senator from Vermont in his race for the Democratic nomination against former Secretary of State Hillary Clinton. "Do you feel the bern?" her message to other Tinder users read, parroting a Sanders campaign slogan. "Please text WORK to 82623 for me. Thanks."
